Hi everyone,
I recently looked into the RRU-Wiki and saw that the BLX-Format is still unkown, so I decided to share my knowledge with you. It contains 16*16 Images for the *.map file with the same name. One Images for each possible tileid. I guess they were used for the editor.
I figured out the format by examining it with a hexeditor. All values are encoded in Little Endian.
Header: "BLX " (4 Bytes, note the Space)
Number of Images (4 Bytes)
Width (4 Bytes)
Height (4 Bytes)
Unkown (4 Bytes, I guess this is some kind of Id for for Format, for example 11 for the surface map)
Unkown (4 Bytes, I guess this is the file version)
Images (BGR565)
If you don't want to encode the files yourself, I attached some samples + testprogram + source code (PureBasic, should work with demo). The Testprogram converts all *.blx files in the same directoy to *.png.
